What is solid state brewing?

Solid liquor-making method refers to the fact that when brewing liquor, the raw materials of liquor-making exist in solid state in the main processes such as cooking, saccharification, fermentation and distillation. Solid liquor-making method generally takes grain as raw material, and its quality is higher than that of liquid wine and solid-liquid wine.

Traditional solid liquor production is made by using sorghum, rice, glutinous rice, corn, wheat and other raw materials, solid state saccharification and fermentation, open production, natural microorganism inoculation and koji making, dry distillation and distillation, pottery jar or wine sea storage and aging and a series of unique technologies and equipment.

Solid-state method is only a method of brewing wine, and it can't simply refer to any type of wine. Pure grain solid-state fermented wine is a kind of white wine which adopts completely traditional brewing technology, takes grain as the main raw material, adds distiller's yeast after crushing, naturally ferments for a certain period of time in mud ponds or pottery jars, and is distilled at high temperature.

Solid state fermentation in cellar:

Liquor brewed by solid-state circulation in the production of ingredients, steamed grain, saccharification, fermentation and steamed wine can be called solid-state fermented wine, and reasonable biotechnology is encouraged to improve the quality of fermented grains.

Distillation mainly uses retort as a container (semi-solid method) for slow distillation, sorting wine according to quality, warehousing in batches, or taking measures such as pouring yellow water and wine tail into the bottom of the pot for distillation.

Saccharification starter used for brewing Qu liquor is enriched and expanded in different raw materials by relying on various wild bacteria or single strains brought in by nature during the manufacturing process, and the corresponding beneficial microorganisms for brewing are preserved. And then air-dried or dried and stored to obtain the finished sake koji.
